Product details
The LSXHR 103mm Intake Manifold's interchangeable velocity stacks allow for the fine tuning of the LSXHR's powerband. Available in tall, medium and short, these stacks can be mixed and matched to improve performance and also to fine tune an engine on a cylinder by cylinder basis. The LSXHR tall velocity stack set promotes the production of more torque and horsepower in the lower RPM operating range. This stack set fits both the LS3 and LS7 LSXHR manifolds.
